A few weeks ago, I wrote an article sharing how to read driver’s license information from PDF417 on Android. Comparing to building an Android native camera app, building a web camera app is much easier. In this article, let’s take a glimpse at a JavaScript sample, which is implemented with a few lines of code by invoking Dynamsoft JavaScript barcode SDK.

JS Barcode SDK Installation
Free PDF417 Generator: This free online barcode generator creates all 1D and 2D barcodes. Download the generated barcode as bitmap or vector image. PDF417 is a 2D barcode symbology (two-dimensional barcode) with very high data density. A single PDF417 symbol can be imagined as multiple linear bar-codes (called 'rows') stacked above each other. This is the reason why the PDF417 symbology is sometimes called a 'stacked linear symbology'. The overall shape of a PDF417 is rectangular.
The JavaScript barcode library is available for download on npmjs.org.
You can either download the package via
or include the online JS file directly:
Building a Web Barcode Reader in less than 30 Seconds
Dynamsoft JavaScript barcode SDK is based on WebAssembly, which brings the high performance of barcode scanning functionality to web developers. Besides, it provides built-in camera module APIs. With the deeply encapsulated JavaScript SDK, you will find making an HTML5 barcode reader with cameras can never be such convenient.
To quickly build a web barcode reader, you just need to copy the following code to your HTML file:
Note: you have to get a free trial license to substitute the PRODUCT-KEYS.
If you have updated Microsoft Edge, Chrome, or Firefox to the latest version, you just need to open the HTML file by double-clicking rather than make any web server deployment.

For better balance the accuracy and performance of decoding PDF417 symbology, you’d better make some parameter configurations according to the online documentation:
The last thing is to create a JavaScript parser for extracting driver’s license information based on the AAMVA standard:
To save time, you can use alert() to show driver’s license information:
